Furthermore, in order to solve the problem in the prior art that ordinary samplers are prone to residual water droplets on the inner wall of the sampler during multiple sampling and detection, resulting in the subsequent sample being contaminated by the previous sample, the present application designs a cleaning structure 6.

A connecting belt 407 is sleeved and connected between the rotating wheel B406 and the rotating wheel A404. Through this technical solution, when the device is set on the surface of the water body, the water wheel 403 will enter the water body, and then the movement of the water flow can drive the water wheel 403 to rotate, and then the rotating wheel A404 can be driven to rotate. The rotation of the rotating wheel A404 can drive the connecting belt 407 to move, thereby driving the rotating wheel B406 to rotate, and further driving the driving wheel 409 to rotate through the rotating wheel B406. Through the above technical solution, the function of automatic rotation of the driving wheel 409 driven by the water flow is realized, and the faster the flow rate of the water flow, the faster the speed of the driving wheel 409. A cylinder 410 is fixedly connected to the side wall of the driving wheel 409, the fixed slide rail 411 is fixedly arranged on the upper surface of the fixed platform 1, a guide groove is opened on the fixed slide rail 411, a guide slider 412 is slidably connected to the guide groove of the fixed slide rail 411, a limiting frame 413 is fixedly connected to one side of the guide slider 412, the limiting frame 413 extends to the cylinder 410 and slidably cooperates with the cylinder 410, and a lifting rod 414 is fixedly connected to the other side of the guide slider 412. Technical solution, the rotation of the driving wheel 409 can drive the cylinder 410 to rotate, and then the rotation of the cylinder 410 can drive the limit frame 413 to move back and forth up and down, thereby driving the guide slider 412 to move, and then driving the lifting rod 414 to move back and forth up and down. Through the up and down reciprocating movement of the lifting rod 414, the sampling structure 5 can be driven to descend into the water body for sampling, and can also be driven to rise to test the sampled water sample, thereby realizing the function of automatic sampling and testing, without the need for additional electrical equipment, and saving resources.

[0027] For specific technical solutions, please refer to Figure 5As shown, the sampling structure 5 includes a fixed seat 501, a rotating rod 502, a sampling cup 503, a ratchet part 504, a gear 505 and a rack 506. The fixed seat 501 is fixedly arranged at the bottom end of the lifting rod 414. The fixed seat 501 is rotatably connected to the rotating rod 502. The sampling cup 503 is fixedly connected to one end of the rotating rod 502, and the ratchet part 504 is fixedly connected to the other end of the rotating rod 502. Through the technical solution, the sampling cup 503 can be driven to reciprocate up and down by the up and down reciprocating motion of the lifting rod 414. When the sampling cup 503 descends, it can enter the water body for sampling. The water sample enters the sampling cup 503. When the sampling cup 503 rises to a high place, the sample can be detected by the detection component 7, thereby realizing the function of automatic sampling and detection.

[0028] As a preferred technical solution, please refer to Figure 6 As shown, the interior of the fixed seat 501 is provided with an inner cavity, and a round head pin 5011 is slidably connected in the inner cavity of the fixed seat 501, and a limiting spring 5012 is fixedly connected at the upper end of the round head pin 5011, and the limiting spring 5012 is in a compressed state. A circular groove 5021 is fixedly connected at the arc-shaped wall of the rotating rod 502, and the round head of the bottom end of the round head pin 5011 is tightly pressed against the circular groove 5021. Through the technical solution, the rotating rod 502 can be kept fixed by the limiting effect of the round head pin 5011 on the rotating rod 502, thereby keeping the sampling cup 503 fixed.

[0029] For further technical solutions, see Figure 7As shown, the ratchet portion 504 includes an outer rotating wheel 5041, an inner ratchet 5042, a pawl 5043 and a connecting spring 5044, the outer wall of the inner ratchet 5042 is rotatably connected to the outer rotating wheel 5041, the inner ratchet 5042 is fixedly connected to the rotating rod 502, the arc-shaped inner wall of the outer rotating wheel 5041 is rotatably connected to the pawl 5043, one end of the pawl 5043 extends to the inner ratchet 5042, one end of the connecting spring 5044 is fixedly connected to the side wall of the pawl 5043, the other end of the connecting spring 5044 is fixedly connected to the inner wall of the outer rotating wheel 5041, and the arc-shaped outer wall of the outer rotating wheel 5041 is fixedly connected to the rotating rod 502. The wall is fixedly connected with a gear 505, and the rack 506 is fixedly arranged on the upper surface of the fixed platform 1. The rack 506 and the gear 505 are meshed with each other. Through the technical solution, when the lifting rod 414 rises from the bottom, it can drive the gear 505 to move upward along the rack 506, so that the gear 505 rotates counterclockwise, and the rotation of the gear 505 drives the outer rotating wheel 5041 to rotate counterclockwise. Due to the setting of the pawl 5043, the counterclockwise rotating torque cannot be transmitted to the inner ratchet 5042, and further cannot be transmitted to the rotating rod 502, thereby keeping the rotating rod 502 in a non-rotating state, and also The sampling cup 503 can be kept rising steadily so that the water sample inside can be tested. When the lifting rod 414 descends, the descent can drive the gear 505 to move down along the rack 506. The number of teeth of the gear 505 and the rack 506 match each other so that the gear 505 rotates a complete circle when moving along the rack 506, so that the gear 505 itself rotates a circle clockwise, so that the outer rotating wheel 5041 rotates clockwise, and then through the setting of the ratchet 5043, the torque can be transmitted to the inner ratchet 5042, thereby driving the inner ratchet 5042 to rotate, and then driving the rotating rod 502 to rotate. The torsional force of the rotating rod 502 is greater than the pressure force of the round head pin 5011 pressed against the rotating rod 502, so that the rotating rod 502 can rotate, and after one rotation, the round head pin 5011 is pressed against the circular groove 5021 again, so that the rotating rod 502 remains fixed again. It can be seen from the above description that when the sampling cup 503 descends, when it descends to the position of the rack 506, the sampling cup 503 can automatically rotate one circle, so that the rotation of the sampling cup 503 can automatically dump the residual water sample inside, which is convenient for the next water sampling, and realizes the function of automatically cleaning the residual water sample.

[0030] For specific technical solutions, please refer to Figure 8 and Fig. 9As shown, the cleaning structure 6 includes a fixed cylinder 601, a movable piston 602, a movable guide rod 603, a fixed plate 604, a reset spring 605, a roller 606, an arc plate frame 607 and a protrusion 608.

According to the technical solution, when the sampling cup 503 rotates, the cleaning structure 6 can be driven to rotate by the rotation of the sampling cup 503, thereby driving the roller 606 to rotate. When the roller 606 rotates to the arc plate frame 607, the protrusion 608 can be used to squeeze the roller 606, thereby pushing the fixed plate 604 to move, thereby driving the moving guide rod 603 to move. The movement of the moving guide rod 603 can drive the moving piston 602 to move, and the movement of the moving piston 602 can make the gas in the inner cavity of the fixed cylinder 601 pass through the output pipe 6011 is sprayed into the inner cavity of the sampling cup 503, and the water droplets remaining on the inner wall of the sampling cup 503 can be cleaned by blowing, so that the sampling cup 503 is fully cleaned, avoiding the contamination of the next sample caused by the adhesion of water droplets to the inner wall of the sampling cup 503. When the roller 606 passes over a protrusion 608, the movable piston 602 can be driven to reset through the action of the reset spring 605, so that the fixed cylinder 601 can re-inhale air through the input tube 6012, and then when passing the next protrusion 608, the gas is sprayed again. It can be seen from the above technical solution that when the sampling cup 503 rotates, it can be automatically sprayed multiple times to achieve a better cleaning function, so that the water droplets on the inner wall of the sampling cup 503 can be fully cleaned.
